Flywheel
A self-reinforcing growth loop where each element of the business drives the next — the more the flywheel spins, the harder it becomes to stop.
Jim Collins popularized the flywheel concept in 'Good to Great.' In startup contexts, a flywheel is a virtuous cycle where growth in one area compounds into growth in another. Amazon's flywheel: lower prices → more customers → more volume → lower costs → lower prices.
Flywheels are distinct from linear growth models. A company with a true flywheel generates compounding returns on its investments — each new customer makes the product better or cheaper for the next customer. Network effects are one type of flywheel.
In Practice
Airbnb's flywheel: more guests → more bookings → more income for hosts → more hosts list → more selection → more guests. Each turn of the wheel makes the marketplace more valuable. This is why marketplace businesses are so hard to compete with once established.
Why It Matters
Investors pay premium multiples for companies with clear flywheels because they represent compounding, defensible growth. Identifying whether a startup's growth is linear (each customer acquired at the same cost) or flywheel (each customer acquired more cheaply over time) is one of the most important early-stage evaluation questions.
